Piaggio Purejet Oilpump bleeding-bit

thingiverse

You can bleed oilpump of Piaggio Purejet and Hiper2 Motors. At the Purejet Motors you cannot mix oil into the gas because of the injection system. The Oil wouldn't achieve crank bearings as its only injected in the combustion chamber. First bleed the oilpump from the oil tank by screwing out the philips-screw with the red sealing ring. Wait until oil pours out constantly. Second get out the oilpump by loosing the two philips-screws. Third use the bit with a cordless screwdriver (clockwise turning), drill with highest rpm you can achieve and engage the gas slider to get air out faster. Wait until the oil hose is filled completely until the motor intake (about 5 mins). Reassemble and have fun.
